Layout Cell Collapse Broken when inside Tabbar


Please review the below snipplet.

The issue that I am having is that the Templates cell should toggle between collapsed fully and expanding to 300px. Instead, its collapsed height is 300px and expanded height is even larger.

If the Layout component is not inside a tab, cell collapse works perfectly.

Please let me know if I am missing something or if there is a workaround that I can use until there is a fix.

Kind Regards,
